7 '0 all whom it may doncern;

Be it known that I, JOHN THOMAS FRED- ERICK BANTJns, a subject of the King of Great Britain and Ireland, residing at Klerksdorp, Transvaal Province, Union of South Africa, have invented a new and useful. Tool Head and Handle Construction, of which the following is a specification.

My invention relates to a new and useful tool and is particularly directed to the construction of the handle and its connection with the head of the tool.

In accordance with my invention, the

' head of the tool is provided with suitable shoulders as by means of a groove or set of grooves, slot or'set of slots cut or otherwise formed in the head and the end of the handle constructed in correspondence with such shoulders, z. a, groove or set of grooves, or

slot or" set of slots. In the preferred form of the invention the handle is positioned relative to such shoulders by sliding the handle relative to the head of the tool, and the handle fixed to the head of the tool by means of rivets, screw bolts or the like.

Further features and objects of the invention will be more fully understood from the following description and the accompanying drawings, in which Figure 1 is a side elevation of a pick head embodying my invention; and

Fig. 2 is a perspective view of the same;

Fig. 3 is a perspective view of a handle constructed in accordance with my invention and adapted to be fixed to the pick head shown in Figs. 1 and 2;

Fi 4c is a perspective view of the as semb ed handle and pick head embodying my invention;

Fig. 5 is a perspective view of a head of a hammer embodying my invention; and

Fig. 6 is a perspective view of the assembled handle and head of hammer shown in Fig. 5;

Fig. 7 is a plan view of a screw bolt adapted for securing my handle to. the head of a tool;

'Fig. 8 is a perspective view of the head of an ax embodying my invention; and

Fig. 9 is a perspective view of the assembled ax and handle embodying my invention.

Referring to Figs. 1, 2 and .3, the pick 1, having the pointed ends 2, 3, is provided with the grooves 4, shown positioned on the opposite faces of the body of the pick 1, such grooves being formed dovetailed by means of the reentrant, oppositely disposed shoulders, shown integral with the central portion of the head 6 of the pick 1.

The handle 7 is providedwith a bifurcated end formed by corresponding portions or lugs, 9, 9, oppositely disposed to provide the groove 8 adapted to receive the central portlon 6 of the pick 1. The terminal portlons or lugs 9, 9, are flared in correspondence with the reentrant angle of the shoulders 5, 5, wherebyupon sliding the handle 7 in position on the head of the pick 1,.the end faces of the terminal portions, or lugs 9, 9, make a tight fit with the prongs 5, 5, respectively. The handle may be provided with the openings 10, 10, correspond to and adapted to register with the openings 11 in the head 6 of the pick 1, to receive a screw bolt 12 ,(see Fig. 7 or other suitable Ineansfor aflixing the handle 7 to the pick 1,- as indicated in the assembled view shown in Fig. 4.

In Fig. 5. I'have shown another form bf my invention namely, a claw hammer 14: having the head 15 and claws 16 and similarly provided at its portion 6 with the groove 4 formed by the shoulders 5. The

portion 6 of the hammer 14 may be similarly provided with the openings 11, 11, as

aforesaid. The assembled handle 7 and or like metal and when not wholly of metal,

the length can be completed by inserting wood into the tube or socket.

The terminal portions or plugs of the handle, and the prongs of the heads of the tools may be cut, molded or otherwise formed.

The one-piece or integral construction of the connection of the handle with the head attains the important advantage of insuring the life of the handle for a period at least equal to the period of the head of the tool and by means of the construction of the 00- handle, slipping of onerelative to the other is entirely obviated.

I claim'- 1. In a tool, the combination of a head having dovetailed recesses on'opposite sides thereof, a metallic handle with bifurcated end, the two legs of said bifurcated end being shaped to fit snugly within the dovetailed recesses of the head, and means for securing said handle to said head.

2. In a tool, the combination of a head having substantially dovetailed recesses on opposite sides thereof, a tubular or hollow metallic handle, one end of which is bifurcated and the two legs at said bifurcated end being shaped to fit snugly within said recesses of the head, and means for securing said handle to said head substantially as described.
